Senior Laser Scientist, Quantum Sensing

About us Founded in 2017, Q-CTRL has grown to become the global leader in quantum. We're using control to solve the hardest problems facing quantum technology, improving hardware performance and accelerating pathways to useful quantum computers and other technologies. As a product-led company, we bring together diverse teams such as product, design, engineering and research to help achieve our mission of making quantum technology useful. Join us to help shape the quantum future. As one of the fastest growing companies in the quantum sector, we've had a number of key milestones: - In November 2023, we announced an industry-first partnership with IBM Quantum Services, natively integrating our performance management software with all IBM quantum computers. Building off of this relationship, in September 2024 we started offering two services via IBM's new Qiskit Functions Catalog as an inaugural partner. - Designed and moved our Global HQ offices and lab space into the first purpose-built (and award winning) commercial and research facility for a quantum technology company in Australia. - Continued to deliver real world outcomes across the quantum sectors, with our work with Australian Defence on software-ruggedized quantum sensing for navigation without GPS, as featured in the New York Times. - In October 2024, we announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital. - Grew our global presence to include Los Angeles, Berlin, and Oxford - as well as the recently announced office in San Francisco. From educating the workforce on how quantum computing works, to building the next generation of quantum sensors, to delivering massive performance gains for end-users, it all starts with hiring the right talent. If you want to help us build the Quantum future, read on. About the role As a Laser scientist within the inertial team, you'll be responsible for developing the next generation of laser systems that operate our state of the art mobile quantum sensors with a focus on field trials and deployment. What you'll be doing:

• You will be part of an established and growing team focused on quantum sensing for a variety of industry sectors such as Aerospace, Defence, geophysical exploration and Earth observation.
• Develop state-of-the-art laser systems for quantum atomic sensing hardware with a focus on miniaturisation and field deployment.
• You will work closely with the broader Quantum Sensing division and leverage the deep expertise of our quantum control engineers in collaboration with our hardware development teams.
• You'll develop and analyse device designs, operational mechanisms, and control solutions for quantum sensors based on cutting edge hardware.
• Interact with hardware partners for the integration of control techniques for sensor operation and data fusion.
• Improve sensor performance in realistic environments by creating and designing highly agile and robust laser systems.
• Other duties within the Employee's skills and experience, or with reasonable training.

Ideally you'll have:

• A PhD in Physics, Engineering or a closely related discipline.
• Experience working with fibre and free space laser systems.
• Experience in, or capability and motivation to learn atom optics, atomic interferometry or quantum sensing, cold atom systems, gravimetry, etc.
• Experience with laser system design, construction and testing.
• Heavy weighting will be given to experience in designing and building ruggedised optical, laser, and photonic systems for field deployment.
• Experience in scientific device design, construction, commissioning, operation and data analysis of scientific devices.
• Finally, you will have a strong desire to work with a world leading team and a company that is fundamentally building the future of the quantum technology industry.

It would be fantastic if you have these skills but not essential:

• Experimental cold atom physics or quantum optics track record (Hons/Masters/PhD).
• Knowledge and experience with fibre and electro optics @ 780nm, 832nm and 1560nm (telecoms knowledge considered).
• Practical experience with digital hardware and software for agile RF and Microwave synthesis and control.
